there are plenty of examples of physical damage to the mind causing downright bizarre cases like split-brains, phantom limbs, all that kind of stuff that verk's about (see
this). and, you know, like when stuff happens to your head like, idk, nature or genetics or whatever you want to call it, brain damage or trauma of any sort, you might see some problems like dying or [open DSM IV and insert disorder here] or any other sort of thing. or how about that mindmapping business they do with MRIs and all that, where they see how your brain lights up when influenced by certain stimuli? hell, that opens up the question of what's it like for another person to think, and how is that influenced by the physical framework we've got to work with -- tangent, whatever, what i'm saying is that I think the odds are pretty clearly in the favor of the mind BEING the brain. i think i would go so far as to say that the brain, the physical matter in your head, gives rise to the mind, but i don't know if i want to go so far as to say that the mind is a completely different thing, substance, material, whathaveyou, than the brain.
i don't want to go anywhere near the functions of the brain, that stuff is far too dangerous, but yeah. if you rly wanted to know.
